WINDOW-SCREEN.

Application fired April 16,

To all whom it may concern:

Be it known that 1, CHARLES J. BARKER, a citizen of the United States ofAmerica, residing at Columbus, in the county of- Franklin and State ofOhio, have invented certain new and useful Improvements inWindow-Screens, of which the following is a specification.

My present invention relates generally to window screens, and moreparticularly to that type of screen including expansible andcontractible sections whose relative movement admits of adjustment towindows of different widths, within aconsiderable range, and is moreespecially a lasting durable metallic screen in which provision is madefor the ready renewal-of the screen mesh which as well known soon rustsand wears out requiring the frame to be discarded along with the wornout mesh under ordinary circumstances. The object of my invention istherefore the provision of a screen which includes a frame so formed asto be capable of effective use and to receive renewed sections of screenmesh, and a further object is the provision of a frame which may be heldagainst rattling in a window casing and adapted to various. positions,as well as one having means for supporting and holding fabric to form aventilating device.

In the accompanying drawing illustrating my invention and forming a partof this specification,

Figure 1 is an elevation of my improved window screen looking from theinside,

Fig. 2 is a horizontal section taken on line 22 of Fig. 1,

Figs. 3, 4 and 5 are vertical cross sections taken respectively on lines3--3, 44 and 5-5 of Fig. 1,

Fig. 6 is a side view of one of the screen meshsections,

Figs. 7, 8 and 9 are vertical sections, more or less diagrammatic,illustrating the practical application of my invention,

Fig. 10 is an elevation showing the use of the device as a ventilator,and

Fig. 11 is an edge view of the fabric strip used in Fig. 10.

Referring now to these figures my in vention proposes a window screenincluding a pair of relatively shiftable U-shaped frame sections 10 and11, each of which has upper and lower bars and an outer upright barSpecification of Letters Patent.

in the form of channels opening inwardly to receive the reinforced edges12 of a rectangular section 13 of screen mesh; The upper and lower barsof the frame section 10 have flanges 14 extending outwardly from theirinner edges and in offset parallel relation to their inner surfaces,adapted to slide in the channels of the upper and lower bars of theframe section 11 as seen particularly in Figs. 3, and 4 so that the tWosections may thus be readily shifted with respect to one another and thescreen as a whole expanded and collapsed in this ing widths. v

Along their upper cross bars the two frame sections 10. and 11 haveoverlapping laterally projecting flanges 15 so as to adapt the same forcontact with the outer surface of an inner sash as at 17 in Fig. 7 whenthe outer vertical bars of the screen frames, are disposed in the lowerportion of the casing guide 18 of the upper sash 19.

The vertical bars of the two frame sections 10 and 11 have verticallyspaced projections 20 upon their outer surfaces so as to adapt thescreen frame to the width of the window guide 18 and prevent rattling ofthe screen, and these vertical bars are also provided with upwardlyextending and inwardly offset upright rods or standards 21 upon theirinner surfaces adapted, when the screen frame is'utilized as in Fig. 9,to receive and support the ends of a fabric strip 22 in order to form aventilator beneath the inner sash 17. For this purpose the strip offabric 22 may have one end turned back and secured upon itself as at 23to receive one of the upright rods or standards 21, and may have itsother end 24 turned back around the other rod wise fastened.

. As seen in Fig. 4 there is suflicient room within the upper and lowerchannel bars of the frame section 11 to receive the upper and lowerreinforced edges 12 of its respective screen mesh section 13, and alsothe flanges 14 of the frame section 10 so that it is obvious it issimply necessary to pull the two frame sections free of one another inorder to remove either or both of the mesh sections therefrom andsubstitute others, and in this respect and in respect to its formationof a fabric covered window ventilator as in Figs. 9 and 10 my inventionPatented Sept. *7, 1920.

manner to fit window casings of vary and pinned or otherthus presentsimprovements which are practical in their nature and will be effectiveand efiicient in use.

I claim:

1. A- window screen including a frame having a pair of oppositely andinwardly opening U-shaped frame sections movable relatively to oneanother and each comprising upper, lower and outer side channel bars,and screen mesh sections having reinforced edges and removably disposedin the channel bars of the said frame sections, the inner reinforcededge of each mesh section forming a brace between the inner free ends ofthe upper and lower bars of its respective frame, as described.

2. A window screen including a frame having a pair of oppositely andinwardly opening U-shaped frame sections movable relatively to oneanother and each comprising upper, lower and outer side channel bars,screen mesh sections having reinforced edges and removably disposed inthe channel bars of the said frame sections and acting as bracestherefor,-one of said frame sections having its upper and lower barsprovided with out turned flanges offset therefrom at one side to movablyextend into the channels of the side bars of the other frame section.

3. A window screen including a frame having a pair of oppositelyv andinwardly opening U-shaped frame sections movable relatively to oneanother and each comprising upper, lower and outer side channel bars,screen mesh sections having reinforced edges and removably disposed inthe channel bars including vertical side bars,

of the said frame sections and acting as braces therefor, one of saidframe sections having its upper and lower bars provided with out turnedflanges offset therefrom at one side to movably extend into the channelsof the side bars of the other frame section, and said frame sectionshaving lapping angular flanges extending along the major portions oftheir upper bars as described.

4. A window screen including a pair of relatively movable U-shaped framesections, eachincluding upper and lower bars and outer vertical sidebars, screen mesh sections having reinforced edges disposed in saidsections, the inner edges of which form braces between the free ends ofthe upper and lower frame bars, said side bars being provided withvertically spaced laterally extending projections at one side adaptingthe frame to snugly interfit a window guide as described.

5. A window screenicomprising a frame and supporting uprights secured inspaced relation to the inner surfaces of the said side bars for thereception of ventilating fabric.

6. A window screen including a frame having vertical side bars,supporting uprights secured to the lower portions of the inner surfacesof said side bars in spaced relation thereto, and a strip of ventilatingfabric having its ends secured around the said uprights, for the purposedescribed.

In testimony whereof I have affixed my signature. 7
